Welcome to the forums! I've played just about every mod and game out there that has anything to do with Star Wars (even a SW mod for Mount and Blade)... and this is one of the best ones yet.
That said, you should go grab this game (2142) from EA for $19.99 and try it out. I bought the game specifically for this mod after following it for some time.
The other above mentioned mods sound great... but I just don't know. I looked at the New Era mod and it looks like a jumbled mess of prequel and original trilogy content and not a whole lot done by the look of their forums. Might be impressive in the end, but it's still going to be a Source mod. So, gameplay will likely be arcade style run and gun unless they tweak some realism settings into it.
The way this mod is now, it's very hard to run amok Counterstrike style. Which is good for me! I can't stand CS.
But definitely go get started, add me to X-Fire (gauwynvorec), and I'll join you in a game or two, three, or more.
